Heat Recover Hot Water Boiler

HEAT RECOVERY BOILERS - Thermopedia

The convective elements of boilers fired by municipal industrial or other waste materials are often referred to as heat recovery boilers although, apart from their geometry, they are more akin to the rear end of a furnace-fired boiler. Perhaps the most common heat recovery boiler is now the gas turbine heat recovery boiler.

What is a Waste Heat Boiler? (with picture)

2020-3-9 · A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.

condensing steam boilers, hot water boilers, gas fired

The condenser is used to recover the waste heat from the exhaust gases to increase the feed water temperature, so that the thermal efficiency can reach over 98%. With equal gas consumption, the more heat the condenser recovers, the higher the thermal efficiency of the boiler will be.

Heat Recovery from Boiler Blowdown TDS Control

Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.
